partial purification of tumour-specific transplantation antigens from methylcholanthrene-induced murine sarcomas by immobilized lectins. | plasma membranes isolated from two immunogenic, non-cross-protecting, mc sarcomas were shown to retain the specific rejection antigens of whole cells as well as serologically detected h-2 antigens. solubilization of the membranes with sodium deoxycholate gave quantitative release of h-2 and retained the rejection specificity of the tumour from which it was derived. polyacrylamide-gel electrophoresis (page) showed no extensive degradation of membrane components during solubilization. the solubili ... | 1999 | 93484 |
[ecg changes in chronic polyarthritis compared to a healthy control group]. | ecg from 200 patients with radiologically and clinically definite rheumatoid arthritis were compared with those from a healthy group with the same age and sex distribution. the frequency of pathological changes of the ecg was found to be the same in both groups. therefore doubt remains whether the pathological changes of the ecg can be attributed to rheumatoid arthritis. | 2000 | 92110 |

the under-reporting of alcohol use: the role of organic mental syndromes. | the under-reporting of alcohol use has been viewed as the consequence of alcoholic denial. alcoholic denial has been conceptualized as an unconscious ego defense. in this paper the authors present data suggesting that the under-reporting of alcohol use may be, in certain cases, the result of the influence of the organic mental syndromes commonly associated with alcoholism. | 2013 | 4053972 |

varied appearance of cardiac pseudoaneurysms on blood pool images. | three cases of cardiac pseudoaneurysms were presented, with findings at the time of gated blood pool imaging. in only one of three was there the finding of a small neck connecting the ventricular cavity with the pseudoaneurysm. in the other two patients, there was a considerably larger communication. the size of the pseudoaneurysm itself was also of little diagnostic assistance. in one case it was small, while in a second patient it was larger in size. the third case revealed a pseudoaneurysm of ... | 2013 | 3595025 |

why aged men become impotent. | despite frequent erectile impotence in aged men, etiologic data are scarce. we evaluated 121 impotent male veterans (mean age, 68 +/- 5.3 years) to obtain information on potential pathophysiologic mechanisms. subjects related a complete medical history and underwent physical examination, metabolic assessment, nocturnal penile tumescence monitoring, and vascular and neurologic assessment. the most frequent cause of impotence was the coexistence of neurologic and vascular disorders (30.3%). other ... | 2009 | 2786397 |

final maturation and ovulation provoked by supply of homologous hypophysis in hoplias m. malabaricus (pisces, erythrinidae). | the final maturation and the ovulation were induced in recently collected specimenes of hoplias m. malabaricus that show oocytes with complete vitellogenesis, by using homologous hypophysis. the hormonal supply was a gradual and positive results were obtained with 9 to 10 hypophysis/kg injected according to 3 different methods. the time of oocytes' maturation from the first dose ranges between 32 and 60 hours a 18 degrees c. the stages of maturation of the oocyte were controlled by intraovaric c ... | 2009 | 2762598 |
single unit response of suprachiasmatic neurons to arginine vasopressin (avp) is mediated by a v1-like receptor in the hamster. | a large population of local circuit neurons within the suprachiasmatic nucleus (scn) exhibit immunopositive staining for arginine-vasopressin (avp). avp has been reported to be released from scn neurons in a circadian pattern that peaks during the subjective day. using an in vitro hypothalamic slice preparation, the present study investigated how scn neurons respond to avp over the circadian cycle and whether the response to avp is mediated by v1- or v2-like avp receptors. exposure of the slice ... | 2009 | 2702494 |
nephrotoxic drugs. | the nephrotoxic effects of cyclosporine, aminoglycoside antibiotics, cisplatin, amphotericin b, beta-lactam antibiotics and indomethacin are reviewed. these drugs were chosen because they are among the most frequent causes of renal injury in children. in addition, their nephrotoxicity is caused by different mechanisms. several generalizations can be made, however. first, agents which cause tubular damage tend to be synergistic in their toxic effects. this synergism is seen when several nephrotox ... | 2011 | 3153061 |
